WHEEL WITH DEMOUNTABLE-RIM FASTENER.

Application filed January 3, 1921.

clare the following to be a. full, clear, and

exact description of the invention such as V will enable others skilled in the art to which it appertains to make and use the same.

Our invention'relates to wheels having demountable rims and is directed chiefly to improved means for detachably securing the demountable [rims to the wheel rims proper. The improved device, while adapted for application to various other types of wheels, is, ,neverthele ss, especially adapted for application to what is known as double disk wheels.

Generally stated the invention consists of the novel devices, and combinations of devices hereinafter described and defined in the claims. 1 5 w i In the accompanying drawings, 'whichillustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a side elevation showing a wheel embodying the invention, some parts being broken away and some parts being sectioned;

Fig. 2 is a vertical section taken approximately on the line 22 of Fig. 1, some parts being shown in full and showing also a wheel spindle and a portion of an axle to which it is pivoted;

Fig. 3 is a fragmentary section on the line 3-3 of Fig. l; and

Fig. 4 is a fragmentary radial section corresponding to Fig. 2 in the line of its section, but illustrating a modified form of demountable rim.

The numeral 5 indicates an axle, such as the front axle of an automobile, to which, by means of the customary pivot bolt 6, a wheel spindle 7 is pivotally connected in the usual way.

The numeral 8 indicates a hollow wheel hub, the same being journaled on the spindle 7 preferably by roller bearings 9 and 10. Said hub, as shown, is provided with a removable hub cap 11 and is held on the Specification of Letters Patent.

spindle 7 in the usual or any suitable way by means of a nut 12.

The hub 8 is provided with a rigidly secured preferably integrally cast hub flange 13 near its inner end and outer annular hub flange let is removably applied to the outer end of said hub. The numerals-15 and 16 indicate, respectively, inside and outside pressed sheet metal wheel disks, the former of which are riveted or otherwise rigidly secured to the xed hub flange 13 and the latter- 0f which engages the inner face of the removable hub flange 14. The two disks are securely clamped together by parallel circumferentially spaced 11bit? equipped bolts 17 that are passed therethrough and also through the hub flanges 13 and 1 1. The hub flange 14 isremovable from the wheel either with or independently of the disk 16.

The numeral 18 indicates an externally threaded arm-adjusting sleeve that is rotativcly mounted on the hub 8 and, at its outer end, is provided with internal gear teeth 19. The gear teeth 19 mesh with a spur pinion 20 that is journaled in the hub 8 and in the outer hub flange 14 and, at its outer end, has an angular shank 21 to which a suitable device, such as socket wrench,

may be applied to rotate said pinion and,

hence, to cause the threaded sleeve 18 to rotate on the hub 8.

lVorking with threaded engagement on the sleeve 18 is a nonrotary internally threaded ring-like nut 22. As a convenient means for preventing rotation of the nut 22, while permitting it to move laterally or axially of the wheel, the rods 17 are passed through circumferentially spaced perforations in said nut.

In the shown and preferred arrangement,

,wheel rim 23 is seated against a shoulder portion of the inside disk 15, and .the said elements, 15, 16 and 23 are further rigidly connected by nut-equipped bolts 24, so that the entire wheel becomes a rigid structure.

Located within the wheel and pivotally connected at their inner ends to the common arm-actuating nut 22, by means oi loose pivot joints 24, is a plurality of radially extended circum ferenti ally spaced ring-cl amping arms 25. The outer ends of these arms 25 are outwardly curved and passed through perforations 26 in the flange of the wheel rim, 23. The outer free ends of the arms 25 terminate in clampin fingers 27 that are adapted to engage the outer side of the demountable rim 28, which, as usual, telescopes freely over the wheel rim proper 23. In Figs. 1 and 2, the demountable rim 28 there shown may be assumedto be either of the straight side type or the clincher type, and it is provided With the usual pneumatic tire 29.

The inner tube of the tire provided With the customary valve stem 30, which projects through a perforation in'the wheel. rim 23 and, hence, is within the inner chain her of the wheel. To .ailord access to this valve stem for the purpose ot'charging the tire, the outside wheel disk 16 .is provided with a port or hand hole that is normally closed by a cover 31, shown as provided with spring prongs 32, which detachably clamp the surrounding edge of the port, (see particularly Fig.

The construction illustrated in Fig. 4- is substantially like that already described, but here the demountable rim 29 1s of a sl ghtly different type and includes a Wedge-acting retaining ring 33 that is directly pressed by the outer ends 0'1. theclampmg arms 25.

Operation.

i The operation is probably evidentpluit ma be briefly described as ttollows;

'l/ hen, by rotation of: the pinionBQ, the

threaded sleeve 18 is rotated in. the proper direction, the non-rotary nut 22 may he movedfrom the full line position into its dotted line position, Fig. 2, and this will rock the clamping arms 25 into i ositious in dicated by dotted lines in Fig. 2, thereby turning the outer ends 27 of said arms radially inward of the demountable rim VVhen the rim-clamping arms 25 are thus moved, they will release the demountable rim 28 and permit the same to be freely slid oil from the wheel rim When the demountable rim is in position on the wheel rim, the threaded sleeve 18 will be rotated in a reverse direction, thereby moving the nut 22 back to its full line position, 2 and this will caueevthe outer ends 27 of the several clamping arms 25, to tightly press against the adjacent edge of the demountable rim 2S and securely hold the sameon the wheel with the opposite side sight.

tures.

viously, only one operation is required to i move all of the several rim-clamping levers to releasing position and only one movement is required to move the same simultaneously rim-securing or clamping positions. il/loi.'eover,-'the various'operative parts, eX- eept the projecting ends 27 of the levers 25, are, in the preferred arrangement of the wheel, located inside of the Wheel where they are protected from dirt and, are out of It should, of course, be understood that the inventlon abovespeclfically described, 111

connection with the drawings, is capable of large range otmod fication With n the spirit of the invention hereingenerally disclosed. a

lVhat we claim is:

u 1. The combination with a wheel having a rim proper and a demountable rim, of a phi :rality of substantially radialcircumferentially spaced rim-clamping levers pivotally fulcrumed on the wheelflstructure adjacent to the rim thereof with their outer ends'proje'cting; for engagementwith said fdernount able rim, an externally threaded sleeve rotatively mounted on the wheel huband held against axial movements, and v an an 'lly movable non-rotary n'utinember workingon saidsleeve and connected to the innere'nds' of said clamping leversfor simultaneously moving'thesame, I I

2, The combinat on w th ivheelhaving I inside and outside'disks, a rim proper and a demountable r11n, 'o'f a plurality of suhstair tially radial circun'rferentially spaced "rimclamping levers located in. the space between said inside and outside disks and pivotally tulcrruned on the wheel structure adjacent to the rim thereof with their outeriends pro jecting for engagement with saiddemoun'table rim, an externally threadedfsleeve rotatively mounted on theivheel'hub between said'disks, pinion operative on said sleeve to rotate the same from the exterior of the wheel, and anon-rotary nut workingon said sleeve and connected to the inner ends of said clamping levers for simultaneously moving the same.
